To all whom it may concern.-

Be it known that I, WILLIAM A. PHILLIPS,

second lieutenant Twenty-second Infantry, United States Army, a citizen of the United States, residing at Fort Keogh,in the county of Custer and State of Montana, have invented certain new and useful Improvements in Lamps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. I

I Figure 1, is a perspective view of a lamp embodying this invention. Fig. 2, is a perspective view of this lamp with parts broken away to show the operative mechanism; the chimney ring is represented as raised. Fig. 3, is a detail in perspective of the operative mechanism detached, showing lamp chimney supports, also guides. Fig. 4, is a perspective view the wick cylinderremoved showing a modification of the means for raising the chimney; the chimney ring being raised and having but one set of chimney supports. Fig. 5, is a central sectional view of the device shown in Fig. 3, showing the chimney ring down, guide armsand guide flanges for the same to steady the up and down movement of the chimney ring. Fig. 6, is a central sectional view the wick cylinder removed of the burner showing a modification of the means for raising and guiding the chimney ring. Fig. 7, is a sectional view the wick cylinder removed showing details of the mechanism for operating the chimney ring, and guiding same and taken at right'angles to view in Fig. 5. Fig. 8, is a detail of a modified form of the connection between the ring and raising mechanism.

This invention belongs to that class of lamps which is provided with mechanism to raise the chimney to get access to the wick, for lighting or trimming, or for any purpose, and for steadying the chimney in its up and down movements, and the points of novelty relate in general to the construction of the several parts and their combination with each other, and in the lamp as a whole, all as will be fully set forth hereinafter and pointed out in the claims.

In the accompanying drawings A, denotes any ordinary coal oil or kerosene Argand lamp or burner which, except as modified by the invention hereinafter described, may be of any usual or ordinary kind, style orstructure. Around the wick cylinder B, is applied an annulus or ring 0. Inside the wick cylinder is the usual foraminous tube 19, which has oil to top the close cap I). This ring 0 can be raised or lowered by means of the crank arm D, the handle end d, of which extends to the outside of the lamp, while its bent part d, moves in the spring loop E, attached to and projecting upward from the side of the ring 0, and so that when the ring is up or down the spring bears against the outside of the wide tube. This ring 0, is connected with the upper and smaller horizontal ring F, aboveit and on which the chimney rests, by the four vertical posts or barsf; the upper portions or ends of these. bars constitute the inside spring chimneyholders. In Fig. 1 on the top of the foraminous bulb a, of the burner is the larger ring G, to which at their lower ends are attached the outer chimney springs g. Preferably the chimney springsf, and g, are nearly parallel with each other, and between them the chimney is held.

In turning the crank D, by means of its handle (1 outside the burner, the spring loop E, acts as a connecting rod to the band C, and pulls the entire chimney frame support up until the crank is at the highest point or dead center. At this position the chimney is supported and the spring holds the crank at the dead center. When it is turned down again the spring holds the crank at the dead center; so that the chimney frame is locked when down or up by the position of dead center of the connecting rod spring. From the band C depend pins 0 which are adapted to enter holes or sockets in the base of the foraminous part of the burner which thus serve to guide the ring in its vertical movement. When the chimney ring is raised, as for instance in Figs. 1 and 3,the wick will be conveniently exposed for trimming or for lighting or for any desired purpose.

In Figs. 3, 4, 5 and 6, is shown a modified structure of the burner, in which the vertical posts on the lower and fixed ring are dispensed with. The chimney ring F in this form of structure is guided inits movements by means of the solid ring F (see Fig. 5 and 6) of the pins a, projecting inward from the foraminous portiona of the burner and passing through the slots 0 of the upright arms 0' at the ends of the semicircular band C. There may also be used with the chimney ring F, to steady and guide it, the rod 9 passing from it through the lower ring of the foraminous part of the burner or into any suitable socket below. Or, instead of or in addition to the band 0, there may be lugs g, depending from the chimney ring F, so as to comeinside the part a of the burner, and these fit into the slotted arms a projectinginwardly from the part a.

Ihave thus illustrated how the chimney ring maybe guided in its up and down movements,

but while I prefer the means now shown for that purpose I do not purpose to limit myself to the precise mechanical structure of parts for the purpose, as now shown.

It will be observed that by means of the crank and the spring loop, the ring or its equivalent,when the chimney ring is operated and guided as set forth, the vertical movements of the chimney are all even and regular, and thus happens because by the mechanism and means shown the pull is always uniform on all sides. considerablemoment because thereby all danger of breaking the chimney is obviated.

It will be noted that by the peculiar mechanism used there is secured a sort of piston action of the ring or semiannular part, upon the wide tube.

What I claim is- 1. In a lamp burner the combination of the crank rod, the ring and spring connected thereto the wick cylinder and the chimney ring, substantially as described.

2. In a lamp burner, as described the combination of the crank rod, the movable part about the wick tube, the spring connection between said part and the crank, and the wick tube, substantially as set forth.

This is a matter of very 3. In an Argand lamp burner, as described the combination of the fixed ring at the top of the foraminous part of the burner, the chimney springs attached thereto, and the movable chimney ring of smaller diameter than the fixed ring, and having chimney springs attached thereto, and the crank and spring piece for moving said smaller ring, substantially as set forth.

4:. In a lamp burner, as described, the combination of the crank rod, the movable part about the tube, the guide rods depending from the same, the spring connection between said movable part and the crank, the wick tube and the chimney support, all substantially in the manner and for the purpose set forth.

5. In a chimney raising device a crank rod connected with the operative parts by means of a spring, in the manner set forth, whereby I in operating the mechanism the spring is at a dead center both when the chimney is up and when down, substantially as set forth.

6. The combination, in a lamp, of the chimney ring, and chimney springs attached there with the band or ring and the spring conwhich the parts are moved, substantially as set forth.

7. In an Argand burner, as described, the combination of a spring connecting the movable part about the wick tube to the crank rod, of the frame supporting the movable chimney ring, fitted with chimney springs and smaller in diameter than the fixed chimney ring at the top of the foraminous part of the burner, so that by turning the crank rod the movable chimney ring slides up and down between the chimneysprings of the fixed chimney ring.

In testimony whereof Iafiix my signature in presence of two witnesses.
